In the drawings, wherein for the purpose y of illustration, isshown a preferred embodiment of my invention, the numeral 20 desigl nates the forward uprights of the body of a closed automobile. Between these uprights and the top 21 is the `usual front opening,

receiv-ng the upper' and lower sections 22 and 23 of the windshield. -.The ,upperwindshield section embodies a generally inverted U-.shaped frame 24, which is an,, gularly` adjustably connected with the uprights 20 by means of'clamping bolts 25. The pane of `glass 26 is held within the lower portion of the frame 24 and is spaced from the top 27 of this iframe, as shown. f The windshield wiper embodies a casing, housing or support,fdesignated as a whole by the numeral 2S. This housing includes a top 29, a. bottom 30, a forward side 31, and a rear side 32,

all of which are suitably connected. The housing further -embodies ends 33 and 34, Figure 2. The ends 33 and 34 are preferably detachably secured to the remainder of the casing or housin so that the several ribs or flanges 38, to enter the grooves 39 in the sides of the frame 24. It is thus seen lthat the housing or casing is held Within the 'f top of the frame 24 in a similar manner to the pane of glass 26, effecting an air-tight joint with the frame 24, and with the top of the glass. It desired, suitable acking may be arranged between the intertting partsf The 'casing or housing is relatively narrow parts may be separate "when desired. Anl i important feature of .the invention .is the `34 are provided with outwardly projecting and beinglocated at the top of the pane of glass 26,- will not perceptibly obstruct the vision of the driver, as the upper portion of 'the' pane of glass is usually covered by a sun visor. Further, the housing is bodily mounted within the windshield fra-me 24, and hence is bodily shiftable therewith and in no way interferes with the usual angular adjustment of the windshield.

`As more clearly shown in Figures 2 and 3, the housing 28 extends forwardly and rearwardly beyond the pane 26. Extending longitudinally within this housing 28, F igures 2 and l3, are spaced'horizontal guide rods4()v and 41, preferably .arranged upon opposite, sides of the.pane26, Thesegui'de rods have their ends suitably attached to to slide longitudinallyof the guide rods, inA

opposite directions.

Arranged rearwardly of the rear guide rod 4() in parallel spaced relation, is a re.

versing screw 45, the ends of which are suitably rotatably mounted upon the ends 33. and 34 vof the housing 28. This reversing screw slidably operates through an opening 46 in the rear end of the carriage 42, and has no screw-threaded engagement with the wall of the opening, as the carriage is capable of being manually shifted'with relation to the reversing screw. The reversing screw has an endless spiral groove embodying oppositelypitched spiral lgrooves 46.

The carriage 42, Figure 4, is provided in its top with a vertical cylindricaljopening 47, for the reception of a vertical movable and rotatable key 48, having a tongue 47" adapted Ato engage within the grooves 46. This key is pivotally carried by a leaf-spring 49,attached-to the carriage at 50and this leaf-spring serves to normally. hold the key in the lowermost position. The carriage is provided with a vertical opening'O, within which is rigidly mounted a tubular stem or support 51, and a shifting rod 52 is slidably mounted within this tubularstem. The upper end of this rod is bent into-a lateral horizontal head 53, which is adapted to enter a recess 54, when the rod is turned to brin the head into a position parallel with vthe ongitudinal axis of -the carriage 42.

This head is arranged directly beneath the leaf-spring 49 and when in this lowermost l osition, does not prevent the leaf-spring holding the key 48 depressed. The rod 52 s bent at its lower end into a laterally eX- tending handle. 55. The rod 52 may be manina shifted upwardly, and turned for a quarter of a revolution and it will then have its head u 53 engaging the surface ofthe carriage, Figure 6. In this position, the head 53 will elevate the key 48 and withdraw vits tongue from within the groove or grooves 46. This will free the carriage from a driving contudinal slot 60, in the bottom 30'. -A depending stein 61 is rigidly secured to the carriage 42 and operates through a. longitudinal slot 62 in the bottom 30 and carries a block 63 rigidly secured thereto. This block carries a resilient arm 64, equipped with a wiper 66 of any well known or preferred type. .A flexible Hap 62 of yleather or the like covers the opening or slot 62 but does not interfere with the movement of the stem 61. The purpose of this flap is to prevent i the air from blowing through the housing,

.Y upon the driver. It is thus seen that a pair of wipers are-provided, to operate upon the opposite faces ofthe pane of glass 26. Power operated means' are provided to rotate the reversing screw 45, including a worm wheell 67 rigidly attached to one end thereof and this worm wheel is driven by a worm/68 attached to an armature shaft 69 of a motor 70, rigidly mounted upon the side 3 2, as shown. A switch 71 isemployed to start .and stop the mot-or.

In viewv ofthe foregoing description, it will b e seen that when the key 48 is in the lowered position, to operate within the gl'oove or grooves' 46 andthe motor 70 is running, that thereversing screw is rotated continuously in one direction, which will cause the carriage 42 t0. travel back and forth for the major portion of the length of the windshield. Both faces of the windshield are thus properly wiped. When it is desired tooperate the device manually the motor may be stopped and the rod 52 manipulated to elevate the key 48 and retain it elevated out of the groove or grooves, 46. The operator may grasp the block ,56. 'in the hand and shift the carriage longitudinally in opposite directions.

a Attention is now invited to Figures 7 to 9, inclusive. In these figures, the numeral 72 designates a casing, housing, or'support. substantially indentical with the casing or housing 28 and Amounted in the windshield frame 24 in the same manner. The same guide rods 40 and 41 are employed, supporting'the carriage 42, `from which depend the wipers' 59 and 66, as previously explained.

Instead of employing the reversing` screw lll i 1,ee1,152

45, the shifting means embodies an endless element orehain 73, passed about sprocket wheels 74 and 75. The sprocket/wheel 74 is pivoted to one. endof the side 32, and is preferably adjustable to take up slack in the sprocket chain 73, while the sprocket wheel and the lower run may also be supported by a strip of felt mounted in the lower portion .of the casing 72, if desired. This will aid in v making theoperation of the device noise- 7', is adapted to less. The sprocket chain 73 has one lin equipped with a linger or catch 81, rigidly secured to this link, and this'catch, Figure tension or erank.82, formed upon the upper end of a rod 83, slidable within the tubular stem 451. The rod is provided at its lower end with a handle 84. The carriage 42 is provided with a recess or groove 85 extending longitudinally of the carriage, and when the rod 83 is properly turned the crank 82 may enter this groove 85 and will. be locked in a position atv a right angle to the chainv 73, and in the path of travel of the catch or hook 81. The motor drives thechain 73 and the crank 82 will constitute a connection between the chain and carriage whereby the carriage will be-made to travel back Vapld t e desired to manually operate the device, the

of glass 26.

rod 88 is. elevated and the crank 82 removed from the groove 85, and this -crank may be turned for av quarter of a revolution, so'that it is parallel with' the chain 73, Figure 7 and out of the path of=travel of the catch.- 81. The carriage may benow manually shifted.

Attention'is new called to Figures 10, 114

and 12, wherein is shown a third modification of the invention. In these figures the numeral 86 designates a casing,housing or support, substantially identical with the casing or 4housing 28, and mounted in the windshield frame 24, in a similar manner. The numeral 87 designates a carriage, similar to the carriage 42, and slidably mounted upon guide rods 88 and 89, having their ends supported by the housing 86, as shown. These guide rods 88 and 89 are,of course, arrangedupon opposite sides of the pane of glass 26. The carriage 87`is equipped with wipers similar to the wipers 59 and 66, and these u ipers engage opposite sides of the pane In this form of the invention, a reversing screw 90, similar to the screw 45, is pivotally mounted Within the housing 86 but 1s arranged between the guide rods the endless chain 73 by a' engage with a lateral ex-- 'will act upon the-opposite 88 and89..lThe carriage v87,;Figure is provlded in its lowerportion with `an angularly 'arranged'.` cyhndrical 'recess 91,'

is dispensed Vwith and the stem 97 is sub- 'stituted therefor, lwhich is rigidly attached to the carnage. This stem carries the block k 55.

A st/em' 98 isattaohed to the opposite side of the carriage and carries the block 60. The wipers are suspended from these blocks, as described. The ,stem 97 operates 'within a wide longitudinalbo ening 99,

through which access'may'; be ad to the screws 93.- Byremovmg the'plate92 the key 95 and associated elements` may be re,-

moved and the device may be Vmanually o erated. As the opening 99'iseo1nparative y wide, it is `preferredto have the same covered by a flexible stri 100 to prevent air from blowing rearwar 1y upon the'driver.

The screw 90 is driven by worm wheel 101, rigidly secured't-hereto and this worm wheel is driven by a worm 102, carried by an armature shaft 103, of a motor 104, rigidly mounted upon the housing 86.

From the foregoing descriptlon, it is obvious that the motor will rotate the screw 90 continuously in one direction and this screw will move the carriage back kand forth over the pane of glass, whereby the wipers sides thereof.
